Engine Line Up – 1956 Hudson Part III (Packard Engine in a Hudson?) Update

Additional update:

According to The Standard Catalog of American Motors 1902-1987, the AMC V8 was introduced on March 5 (1956) in a new model called the Hornet Special.  It displaced 250 cu. in.  The 2 V8 engines were sold side-by-side until October 25, when the 1957 models were introduced.  The 1957 cars, all of which were called "Hornets", came _only_ with the 327 cu. in. AMC V8 (the Hudson and Nash 6 cylinder engines were no longer available).

Thanks Kevin.


Engine Line Up – 1956 Hudson Part III (Packard Engine in a Hudson?)

I need to finish this one up so here are the V8 offerings for the 1956 Hudson.

Interesting enough one was called the Packard Eight and the other was the Hornet Special Eight.

The Hornet Special Eight was a V8 with overhead valves.  It was a cast iron block that displaced 250 cubic inches.  The bore and stroke were 3.50″ x 3.25″ and a compression ratio of  8.0:1 helped produce about 190 hp.  This was topped by a Carter WGD two barrel carb (Model 235S).

The Packard Eight, was it the really a Packard engine?

What I do know is that the Hudson engine was a V8 with overhead valves and cast iron block.  It sported a bore and stroke of 4″ x 3.50 (which means the bore was half an inch larger than the Special and the stroke was quarter of an inch larger.  This upped the compression ratio to 9.5:1 and displacement up to 352 cid.  Topped with a Carter carb WGD two barrel (Model 2231SA it produced 220 hp.

But was it a Packard engine?

It may have been.  In 1955 Packard powered some of its models with what they called the Clipper Custom or the Packard Line V8 (up until that date any Packard 8 cylinder was an L head).  This engine had the same bore and stroke, compression and displacement (352).  It had more horse power but that was more likely attributed to the 4 barrel Carter carbs that were used (models 2232S or 2284S).  Packard also used Rochester Type 4GC four barrel carbs on some of the models.  So I can’t conclude for certain that it was the same engine, but I believe it was.  I’ll see if I can find the answer with more research.

Engine Line Up – 1956 Hudson Part II

Next up we have Hornet Six and the Hornet Twin-H Six.

The Hornet Six was a cast iron power plant and displaced 308 CID.  Like all the Hudson 6 cylinders this was an in-line L-head.  This had 3 – 13/16 bore and 4.50″ stroke and a compression ratio of 7.5:1 and with a two barrel Carter carb (WDG Model 2252S) it would be the Hornet down the street with 165 hp.

Here a commercial image of the Cater WGD carb.

The Hornet Twin-H Six is basically the same engine, same displacement, bore and stroke, but this was topped with 2 WA-1 Carters (Model 2113S) one barrel carbs.  This set up helped it reached 175 hp.

Engine Line Up – 1956 Hudson Part I

Think there was much of a choice of engines back in 1956?  Well there were a few for the 1956 Hudson.

As was custom back in the 40’s and 50’s, the engines were often named similar to the model of the car they powered.  For the 1956 Hudson, the company had the Hudson Rambler, Wasps and Hornet.  The engines followed suit for the most part.  There were 5 six cylinder versions and 2 V8s.

The first up is the Hudson Rambler Six.  This was an in line 6 L head with a displacement of 195.6 cid.  It was a cast iron block with bore of 3 1/8″ and stroke of 4.25″
and a compression ratio of 7.5: 1.   The four main bearings, solid valve lifters and 1 barrel Carter Carb (YF model 2009s) combined to produce 120 horse power.

The Wasp Six was a In Line L-head 6 cylinder.  It to was a cast iron block same compression ratio 7.5:1.  Its bore and store was larger than the Hudson Rambler – 3.00 x 4.75 (vs. 4.25) and it manged to displace 202 cid without a change in hp still at 120.  The engine came from the factory with a Carter one barrel WA-1 carb (2009s).


The Wasp Twin-H Six was similar to the other Wasp except it managed 8.0:1 compression ratio with the help of the H carb configuration.  This consisted of 2 Carter single barrel carbs (WA-1 model 2013s) that helped the 202 cid engine produce 130 hp.
